Mop



Patented duly l?, i923.

Be it known that I, FREDERICK W.' PEN- Dnnensr; la citizen of thev United States,` residing at Cambridge, in the county of Mitt dleseX and State of Massachusetts', have in Vented new and `useful `Improvements in Mops7 of which the yfollowing is afspecica tion.

This invention relates to a mop adapted to be releasably engaged by clamping-jaws secured to an operating handle, `the jaws and handle constituting a mop head from whichthe acting portion of the mop depends loosely.

The mop is usually composed of fibrous filaments, laid side by side', and bent or folded between their ends to form neck portions and free depending portions, and means confining the neck portions to form a compact oblong shank portion, adapted to be `grasped between the mop head j aws, each filament being usually composed of slack twisted threads or strands of cotton yarn.

The said shank portion has heretofore been limp or fieXible, and capable of being easily bent sidewise at any portion not stiffened by the clamping-jaws, so that if the shank portion projects to any considerable extent from the ends of the clamping-jaws,

the limp projecting portions are likely to be bent by contact with objectsencountered by the mop7 the effective width of the mop being thus reduced. It has, therefore. been considered desirable heretofore to provide clampingjaws coextensive in length with the shank portion of the mop.

My invention has for its object to rein` force and stiften the shank portion of the mop7 so that it may be` made much longer than the clamping-jaws` without liability of y being bent at its projecting end portions. I

n tion hereinafter described and claimed.

attain this object vby the improved construc- Of the accompanying drawings forming a part of this specification,-

Figure 1 is a side View, illustrating the first step in the manufacture of my improved mop. c i

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a side view showing the shank portion of the mop completed.

Figure t is a section on line 4-4 of Fig ure 3.

Figure 5 is a side view on a smaller scale,

'showing the mop engaged with a mop head f whichincludes 'clamping-jawsf` i l f Inl carrying outlniy invention, I thread a "suiiicienffnumber of filaments 12 to consitute a mop'7 through-a metal rii'ig 13', of stout lwire, preferably galvanizediron,V although any 'other suitable ,hetal may be employed. l

rEhe filaments are arranged so that their mid length portions are within the ring, and their end portions depend `from opposite sides of the lower portion of the ring. I then exert pressure on the ring to impart to it the loop form shown by Figure 3, the ring beingthus converted into a vloop member including substantially parallel side portions, andA neck portions connecting the side portions. The filaments 12 are bent across one of the side portions, anddepend therefrom in two series. The bent portions of the filaments are confined between the neck portions of the loop member. Finally I connect the depending portions of the filaments at one side of the loop member with those at the opposite side, by means preferably embodied in a wrapper 14, composed of a strip of webbing wrapped around the depending portions of the filaments immediately below the loop member, and stitches 15` engaged with the wrapper and passing through the interposed filaments. as shown by Figure 4; The mop is thus completed the connecting means, and the filament portions associated therewith, constituting a reinforced shanln adapted to be clamped between the aws of a mop head. and stifi'ened by the loop member 13, so thai; the ends of` the shank may project operatively in opposite directions from the clamping-jaws. In other words, the ends of the shank that may project from the ends of the clamping-jaws are so stiiened by the loop member 13, that they are not liable to be bent by Contact with objects encountered by the mop.

Figure 5 shows the mop above described,

engaged with a mop head, such as that shown by my Patent No. 909.449, dated January 12, 1909` and composed of opposed clamping-jaws 16, (only one of .which is shown), and a handle 17, with which the jaws are adjustably connected by a bolt 18, and a clampingnut 19, It is obvious. however. that the mop may be heldl by a mop head otherwise constructed.

It will be seen that the length of the shank portion of the .mop may considerably parallel side portions 'and neck portions connecting the side portions, the lilaments being threaded throughthe loop member, conined between the neck portions thereof, and bent `across one of the side portions, so that, the free ends of thelaments depend in two series from said side portion, and

means connecting the depending portions at one side of the loop member ywith those at the opposite side, said loop member, the connecting means and thel lament portions associated therewith, constituting a reinforced shank, adapted to be" clamped between mop head jaws, and stiifened by the j loop member, so that the ends of the shank may projectv operatively in opposite directions from the clamping jaws.

In testimony whereof I haVeaiiXed' my signature. h` i l FREDERICK W. PENDERGAST.
